While Sacco had been airborne, her tweet had gone horrifically viral. It had stirred up a storm of smug indignation and gleeful anger. A hundred thousand people had tweeted their condemnation, calling her disgusting, stupid, and racist (for a start). The hashtag #HasJustineLandedYet had trended. “All I want for Christmas,” typed one member of the mob, “is to see @JustineSacco’s face when her plane lands and she checks her inbox/voicemail.” Sure enough, someone took a photo of Sacco arriving in Cape Town, and that went viral. She promptly lost her job.
